The chi-squire test (α=0.10) with the continuity correction will be used for analysis of the primary analysis. For all other comparisons, two-sided analyses will be performed and a p-value of 0.05 or less will be considered statistically significant. 95% confidence intervals will be constructed for outcomes of interest. Descriptive statistics will be used to summarize patient characteristics and outcomes by intervention arm. Differences in outcomes between intervention arms will be compared by using paired t-tests, Wilcoxon rank sum tests or McNemar tests as appropriate. Adjusting for stratification factors will be performed using logistic regression or linear regression. Time-to-event analyses will be estimated using the Kaplan-Meier method, and compared using Cox proportional hazards regression.
